ANTlFRICTION-BEARING FOR WAGON-REACHES.

SPECIFICATION forming part of Letters Patent No. 743,481, dated November10, 1903. Application filed February 24, 1903. Serial No. 144.916. (Nomodel.)

To LZ/.3 whom it may concern: l

Be it known that I, GEORGE W. GARDNER, of Denver, in the county ofArapahoe, State of Colorado, have invented a new and Improved AdjustableAntifriction Ball-Bearing Wagon-Reach; and I do herebydeclare that thefollowing is a complete and exact description of the same. j

My invention is an improved adjustable antifriction ball-bearingwagon-reach; and it consists in the construction and combination ofdevices hereinafter described and claimed.

One object of my invention is to provide a frame of improvedconstruction which is adapted to be detachably secured to a wagonreachof any size and to carry antifriction devices to operate on thesway-barof the front hounds or on a fifth-wheel to reduce friction.

between the reach and the sway-bar or fifthwheel and prevent wear of thereach.

A further object of my invention is to provide improved means forattaching the frame to a wagon-reach and for adjusting it as may berequired to adapt it to fit on the wagonreach.

In the accompanying drawings, Figure lis a top plan view of a portion ofthe front truck ofthe wagon-gear, showing a portion of the reach andshowing the sway-bar of the front hounds on which my improved adjustableframe and antifriction devices operate. Fig.

2 is a detail inverted plan view of the frame.

and the antifriction devices, showing the frame attached to a reach.Fig. 3 is a tra-nsverse sectional view of the same, taken on the planelindicated by the line a c. of Fig. 2. Fig. Ll is a similar view, takenon the plane indicated by the line b IJ of Fig. 3. Fig. 5 is a detailsectional view, taken on the plane indicated by the line c c of Fig. 2.Fig. 6 is a detail sectional view, on' a somewhat larger scale, showing`one end of the upper clamping-bolt, a portion of one section of theframe, and the nut and washer on the clamping-bolt. Fig. 7 is a detailview of the washer.

In the embodiment of my invention I provide a frame l, which comprises apair of side sections 5, each of which is of the form here shown, has aside iiange 5b to bear against one side of a reach A, a base-flange 5cto bear against the under side of the reach, and a longitudinal recessor seat 5d on its under side adapted to receive a plurality ofantifrictionballs 7, which are adapted to turn or revolve in the saidseat and to bear on the upper side of the sway-bar B, as shown in Figs.l, 3, and 4, or to bear on the upper side of a fifth-wheel, as the casemay be.

Each side flange of each frame-section 5 is provided with a verticalcentrallydisposed adjusting-slot 5 and on its outer side, at the.

sides of the said slot, with a series of serrations 5G; A clamping-boltG serves to connect the side flanges of the frame-sections and to bearon the upper side of the reach. Said clamping-bolt extends through theadjustingslots 5a and carries washers 9, which are provided on theirinner sides, opposed to the frame-sections, with tongues or serrations9, adapted to engage the serrations 5e of the frame-sections. 'The headof the bolt .bears against the outer side of one of these washers, andthe nut 6a bears against the outer side of' the other washer, and whenthe nut is tightened on the bolt to clamp the vertical flanges of theside or frame sections rmly against opposite sides of the reach thecoengaging ,serrations 5e 9fL of the said sections and the said washersserve to lock` the bolt iirmly against casual displacement, as will beunderstood. The slots 5 admit of the required vertical adjustment of thebolt G to enable the sections of the frame l to be applied to reacheswhich vary in vertical extent.

The lower ianges 5C of the frame-sections 5 are provided near their endswith'depending lugs 5f and are provided on the inner sides of the saidlugs with recesses 5g.

justing-bolts 8, of which two are here shown as employed, connect thesaid flanges 5C together, the said bolts passing through openings withwhich the lugs 5f are provided, and the nuts 5h of the said bolts beingdisposed in the recesses 5g, which serve to lock them against casualmovement on the bolts. It will be understood that by the provision ofthe flanges 5", which bear against the under side of the reach, and bythe provision of the bolts 8, which adjustably connect the said flangestogether, the space between'the side or vertical flanges of the sections5 may be varied in width, according to that of, the reach Ad-V IOO

to which the frame l is secured. Hence the frame may be rmly secured toa reach of any size.

The balls 7 bear on the svvaybar or fifth- Wheel of the vehicle, reducefriction between the same and the frame l, and entirely prevent Wear ofthe reach, as will be understood.

Having thus fully described my invention, What I claim as new, anddesire t0 secure by Letters Patent, is-

1. A frame comprising a pair of .sections having baseeflanges to bearagainst the under side of a reach, and side flanges to bear against thesides of a reach, said side iianges having vertical adjusting-slots,adjusting-bolt connecting the side iianges together and disposed in saidadj listing-slots, said bolt being adapted to bear on the upper side ofthe reach, adj listing-bolts adjustably connecting the baseflangestogether under the reach, and anti- GEORGE W.
